I would add my voice to the others. I have noticed this all over the world at all sorts of locations. I noticed this just before Christmas, but it really is mcuh worse now. I often get notices saying that it could not find the page or ages to load or to accept posts. In fact it had got so bad that I was actually posting from cut and paste having prepared the text in a word document that could be saved.
I remember Merry using the expression "stable" about Flyertalk and that is what seems to have gone west of late.
I am relieved not to be alone in this as I had noticed that no one on the BA Forum had commented on this.
